Description

Technical Field

[0001] This invention relates to the field of die-cutting technology, specifically to a die-cutting assembly with a fine-tuning mechanism and laser ranging. Background Technology

[0002] Existing slitting devices often involve rotating blades mounted on a cutter shaft to cut sheet-like raw materials into slits. The raw materials are guided to the blades by pressure rollers, and the position of the blades on the cutter shaft is determined by spacers of varying lengths. When the slitting width needs to be changed, the cutter shaft must be replaced with a spacer of appropriate width. Currently, replacing the spacer requires disassembling the pressure rollers and then the cutter shaft, which takes a considerable amount of time. Furthermore, repeated disassembly and reassembly can easily lead to deviations in the precision between the cutting dies, thus affecting the cutting accuracy. This is especially true when fine-tuning is required, as replacing the spacer is not only cumbersome but also makes it difficult to accurately control the adjustment distance of the blades, further affecting the cutting accuracy of the raw materials. Moreover, existing cutting die assemblies do not have devices for real-time monitoring of the blade position. If the blades shift or wobble during the cutting process and are not detected in time, it will result in a large amount of waste, causing losses and affecting normal production efficiency.

[0009] Preferably, the horizontal plate and the convex seat are both disposed below the L-shaped bracket. The two ends of the convex seat are respectively sleeved on the two guide light rods, and the convex seat and the guide light rods are slidably connected left and right.

[0010] Preferably, the fixed base has a movable groove on its side and a rotating groove on its inner side.

[0011] Preferably, both ends of the bidirectional transmission screw are integrally formed on the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages:

[0015] 1. When it is necessary to fine-tune the position of the upper blade assembly left and right, first release the locking mechanism from locking the rotating crown gear. Then, turn the knob to drive the worm gear to rotate, causing the two threaded sleeves on the bidirectional transmission screw to move closer or further apart. Through the micro-component, the transmission mechanism can move left and right, which in turn drives the upper blade assembly to move left and right, thereby adjusting the position of the upper blade assembly. This allows the upper blade assembly to cut the raw material to different widths. The laser displacement detection mechanism detects the distance the upper blade assembly moves in real time, thus enabling accurate fine-tuning of the left and right position of the upper blade assembly to ensure cutting precision.

[0016] 2. After adjustment, loosen the pull ring. Under the action of the locking spring, the locking crown gear engages with the rotating crown gear, fixing the rotating crown gear and thus fixing the micro-component. This, in turn, fixes the transmission mechanism and the upper blade assembly. The position of the upper blade assembly is then monitored in real time by the laser displacement detection mechanism. If the upper blade assembly deviates or shakes during the cutting process, it can be detected in time to prevent damage to the raw materials and further ensure the accuracy of cutting the raw materials.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 8 The present invention provides a technical solution: a die-cutting assembly with a fine-tuning mechanism and laser ranging, including a base plate 1, a lower left support 11 and a lower right support 12 fixedly installed on the base plate 1, a lower die-cutting assembly 13 installed between the lower left support 11 and the lower right support 12, an upper left support 14 fixedly installed on the upper end of the lower left support 11, an upper right support 15 fixedly installed on the upper end of the lower right support 12, and an upper die-cutting assembly 16 disposed between the upper left support 14 and the upper right support 15;

[0028] Two guide rods 17 are symmetrically fixedly connected between the upper left support 14 and the upper right support 15 at the upper end of the upper blade assembly 16. An upper protective cover 18 is fixed across the upper end between the upper left support 14 and the upper right support 15. A laser displacement detection mechanism for detecting the position of the upper blade assembly 16 is installed on the side of the upper left support 14. A transmission mechanism for driving the upper blade assembly 16 to move left and right is installed between the upper left support 14 and the upper right support 15. A fine-tuning component for adjusting the left and right positions of the upper blade assembly 16 and the transmission mechanism is installed at the upper end of the upper left support 14.

[0029] Please see Figure 2The laser displacement detection mechanism includes a protective shell 2 detachably mounted on the side of the upper left support 14, a laser displacement sensor 21 detachably mounted inside the protective shell 2, two detection components 22 distributed on the upper and lower sides of the laser displacement sensor 21, and a power supply 23 detachably mounted inside the protective shell 2. The two detection components 22 are detachably mounted on the upper end and the inner side of the protective shell 2, respectively. The laser displacement sensor 21 is located on one side of the upper blade assembly 16. The laser displacement sensor 21 measures the left and right movement distance of the upper blade assembly 16. When the laser displacement sensor 21 detects, it detects the blade shaft in the upper blade assembly 16. A partition is fixedly installed in the inner cavity of the protective shell 2. One of the detection components 22 and the power supply 23 can be detachably mounted on the partition.

[0030] Please see Figures 1 to 3 , Figure 7 A left circular slot 141 is provided through the side of the upper left support 14, and a left limiting groove 142 is provided at the upper end of the left circular slot 141. A right circular slot 151 is provided through the side of the upper right support 15, and a right limiting groove 152 is provided at the upper end of the right circular slot 151. The two ends of the transmission mechanism are respectively movably inserted into the left circular slot 141 and the right circular slot 151.

[0031] A fixed base 3 is fixedly connected to the upper end of the upper left support 14, and an L-shaped bracket 4 is fixedly connected to the upper end of the upper right support 15. One end of the L-shaped bracket 4 is fixedly connected to the side of the fixed base 3. A T-shaped groove 41 is provided on the L-shaped bracket 4. The transmission mechanism includes a T-shaped plate 5 that is slidably installed in the T-shaped groove 41, a horizontal plate 51 fixedly connected to the lower end of the T-shaped plate 5, two convex seats 52 that are symmetrically fixedly connected to both ends of the horizontal plate 51, two connecting blocks 54 fixedly connected to the sides of the two convex seats 52, a traction block 53 fixedly connected to the side of one of the convex seats 52, a left limiting block 55 fixedly connected to one end of one of the connecting blocks 54, and a left limiting block 55 fixedly connected to the left... The left sliding sleeve 56 under the limiting block 55, the right limiting block 57 fixedly connected to another connecting block 54, and the right sliding sleeve 58 fixedly connected to the lower end of the right limiting block 57 are respectively sleeved on both ends of the upper blade assembly 16. The two ends of the upper blade assembly 16 are rotatably connected to the left sliding sleeve 56 and the right sliding sleeve 58 respectively through bearings. Two annular plates are sleeved on one end of the upper blade assembly 16, and the bearings are set between the two annular plates. The bearings are stably distributed in the inner cavity of the left sliding sleeve 56 through the two annular plates. The two annular plates are fixedly connected to both sides of the left sliding sleeve 56 respectively, so that when the left sliding sleeve 56 moves left and right, it can drive the bearings and the upper blade assembly 16 to move left and right synchronously.

[0032] Both the horizontal plate 51 and the convex seat 52 are located below the L-shaped bracket 4. The two ends of the convex seat 52 are respectively fitted onto two guide rods 17, and the convex seat 52 and guide rods 17 are slidably connected left and right. The left sliding sleeve 56 is movably inserted into the left circular slot 141, and the left limiting block 55 is slidably connected left and right to the left limiting groove 142. The right sliding sleeve 58 is movably inserted into the right circular slot 151, and the right limiting block 57 is slidably connected left and right to the right limiting groove 152. When the traction block 53 moves left and right, it drives the two convex seats 52 and the horizontal plate 51 to move left and right. The horizontal plate 51 drives the T-shaped plate 5 to slide left and right along the T-groove 41, while the convex seat 52 slides left and right along the guide rods 17, thus enabling the two convex seats 52 and the horizontal plate 51 to move stably left and right. The base 52 drives the left limit block 55 and the right limit block 57 to move left and right through two connecting blocks 54. The left limit block 55 and the right limit block 57 drive the left sliding sleeve 56 and the right sliding sleeve 58 to move left and right respectively. The left sliding sleeve 56 and the right sliding sleeve 58 work together to drive the upper blade assembly 16 to move left and right, thereby adjusting the position of the upper blade assembly 16 so that the upper blade assembly 16 can cut the raw material to different widths. When the left limit block 55 moves left and right, it moves left and right along the left limit groove 142. When the right limit block 57 moves left and right, it moves left and right along the right limit groove 152, so that the left sliding sleeve 56 and the right sliding sleeve 58 can move left and right stably. At the same time, the left limit block 55 and the right limit block 57 ensure that the left sliding sleeve 56 and the right sliding sleeve 58 can only move left and right.

[0033] Please see Figures 2 to 6 , Figure 8 The fixed base 3 has a movable groove 31 on its side and a rotating groove 32 on its inner side. A circular groove 33 is formed on the side of the rotating groove 32. Two sliding grooves 34 are symmetrically formed in the circular groove 33. The fixed base 3 is composed of two plates joined together. The fine-tuning assembly includes a bidirectional transmission screw 6 rotatably connected in the movable groove 31, two threaded sleeves 61 symmetrically fitted at both ends of the bidirectional transmission screw 6, two movable rods 62 respectively hinged to the sides of the two threaded sleeves 61, and a mechanism set on the bidirectional transmission screw 6. The worm gear 63 at one end, the rotating crown gear 64 fixedly connected to the side of the worm gear 63, the worm 65 meshing with the upper end of the worm gear 63, the two knobs 66 symmetrically arranged at both ends of the worm 65, and the locking mechanism set in the circular groove 33 for fixing the rotating crown gear 64, the threaded sleeve 61 is slidably connected to the movable groove 31, and the ends of the two movable rods 62 away from the threaded sleeve 61 are hinged to the traction block 53. The worm gear 63, the rotating crown gear 64 and the worm 65 are all set in the rotating groove 32.

[0034] Both ends of the bidirectional drive screw 6 are integrally formed on the rotating shaft. The bidirectional drive screw 6 is rotatably connected to the fixed base 3 through the rotating shaft. The rotating shaft at one end of the bidirectional drive screw 6 passes through the fixed base 3 and extends into the rotating groove 32 and is fixedly connected to the worm gear 63. The worm 65 is rotatably connected to the fixed base 3. Both ends of the worm 65 extend to the outside of the fixed base 3 and are fixedly connected to two knobs 66 respectively. By rotating the knobs 66, the worm 65 is driven to rotate, which in turn drives the worm gear 63 to rotate. The worm gear 63 drives the rotating crown gear 64 and the bidirectional drive screw 6 to rotate synchronously. By rotating the bidirectional drive screw 6 clockwise or counterclockwise, the two threaded sleeves 61 on the bidirectional drive screw 6 move closer or further apart. When the two threaded sleeves 61 move closer together, the movable rod 62 pushes the traction block 53 away from the fixed base 3. When the two threaded sleeves 61 move further apart, the movable rod 62 pulls the traction block 53 closer to the fixed base 3, thereby enabling the traction block 53 to move left and right.

[0035] The locking mechanism includes a locking crown gear 7 slidably connected in the circular groove 33, two sliders 71 symmetrically fixedly connected to the sides of the locking crown gear 7, a slide rod 72 fixedly connected to the sides of the locking crown gear 7, a locking spring 73 sleeved on the slide rod 72, and a pull ring 74 disposed at the end of the slide rod 72 away from the locking crown gear 7. The locking crown gear 7 is engaged with the rotating crown gear 64, and the sliders 71 are slidably connected to the slide groove 34. When the locking crown gear 7 slides along the circular groove 33, the locking crown gear 7 drives the sliders 71 to slide along the slide groove 34, thereby enabling the locking crown gear 7 to slide stably along the circular groove 33.

[0036] The locking spring 73 is set in the circular groove 33. One end of the slide rod 72 extends through the fixed seat 3 to the outside and is fixedly connected to the pull ring 74. The slide rod 72 is slidably connected to the fixed seat 3. The two ends of the locking spring 73 are respectively inserted into the locking crown gear 7 and the inner side wall of the circular groove 33. The locking spring 73 applies a spring force to the locking crown gear 7. Under the action of the locking spring 73, the locking crown gear 7 engages with the rotating crown gear 64, fixing the rotating crown gear 64, thereby fixing the worm gear 63 and the bidirectional transmission screw 6, fixing the micro-adjustment component, and further fixing the transmission mechanism. This prevents deviation or shaking during the cutting process of the upper blade assembly 16, ensuring stable cutting operation of the upper blade assembly 16. At the same time, the position of the upper blade assembly 16 is detected by the laser displacement detection mechanism. If the upper blade assembly 16 deviates or shakes during the cutting process, it can be detected in time to prevent damage to the raw materials. When it is necessary to adjust the position of the transmission mechanism and the upper blade assembly 16 left and right through the micro-component, first pull the pull ring 74 outward. The pull ring 74 drives the locking crown gear 7 away from the rotating crown gear 64 through the slide rod 72. At this time, the knob 66 ​​can be rotated, causing the worm gear 65 to rotate, thereby adjusting the left and right position of the transmission mechanism and the upper blade assembly 16.

[0037] Working principle: When the position of the upper cutter assembly 16 needs to be finely adjusted left or right, so that the die-cutting assembly can cut the raw material with different widths, the pull ring 74 is pulled outward first. The pull ring 74 drives the locking crown gear 7 away from the rotating crown gear 64 through the slide rod 72. At the same time, the locking crown gear 7 compresses the locking spring 73. Then, the knob 66 ​​is turned to drive the worm gear 65 to rotate. The worm gear 65 drives the worm wheel 63 to rotate. The worm wheel 63 drives the rotating crown gear 64 and the bidirectional transmission screw 6 to rotate synchronously. The bidirectional transmission screw 6 rotates clockwise. The needle rotates clockwise or counterclockwise, causing the two threaded sleeves 61 on the bidirectional transmission screw 6 to move closer or further apart. When the two threaded sleeves 61 move closer together, they push the traction block 53 away from the fixed seat 3 via the movable rod 62. When the two threaded sleeves 61 move further apart, they pull the traction block 53 closer to the fixed seat 3 via the movable rod 62, thus enabling the traction block 53 to move left and right. The traction block 53 drives the two convex seats 52 and the cross plate 51 to move left and right. The two convex seats 52 drive the left limit block 55 and the right limit block 55 via the two connecting blocks 54. The limiting block 57 moves left and right, which in turn drives the left sliding sleeve 56 and right sliding sleeve 58 to move left and right respectively through the left limiting block 55 and right limiting block 57. The left sliding sleeve 56 and right sliding sleeve 58 work together to drive the upper blade assembly 16 to move left and right, thereby adjusting the position of the upper blade assembly 16 so that it can cut the raw material with different widths. The distance of movement of the upper blade assembly 16 is detected in real time by the laser displacement detection mechanism, so that the left and right position of the upper blade assembly 16 can be accurately fine-tuned to ensure the cutting accuracy. After the adjustment is completed, the pull ring 74 is released, and the locking crown gear 7 engages with the rotating crown gear 64 under the action of the locking spring 73, fixing the rotating crown gear 64, thereby fixing the micro-component, and then fixing the transmission mechanism and the upper blade assembly 16. The laser displacement detection mechanism is set to monitor the position of the upper blade assembly 16 in real time. If the upper blade assembly 16 deviates or shakes during the cutting process, it can be detected in time to prevent damage to the raw material and further ensure the accuracy of cutting the raw material.
